AFCEE Wurtsmith P&T Risk Mitigation Study <br />The Wurtsmith Air Base I losco, Michigan <br />Technical Review <br />The Wurtsmith Air Base in losco County, Michigan <br />had two overlapping plumes, one of hydrocarbons <br />and one of PFAS materials. Ken evaluated <br />approaches to improve GAC bed life for the <br />groundwater pump and treat system, treating a plume <br />of combined VOC and PFAs. He also supported the <br />study of PEAS from the groundwater. The plume was <br />complicated by anaerobic conditions resulting from <br />the hydrocarbon plume, causing liberation of soluble <br />iron (ferrous iron) that was fouling the GAC bed <br />leading to premature breakthrough. <br />200 West Pump and Treat" I Hanford Nuclear Site <br />Hanford, Washington I Technical Review <br />Ken was involved in the treatment of radionuclides, <br />VOCs, including carbon tetrachloride, hexavalent <br />chromium, and nitrate. He designed the "Centralized <br />Treatment System' for the 200-ZP-1 area, which is <br />the largest treatment system in Hanford. The <br />treatment system will treat up to 3,750-GPM of <br />contaminated groundwater for the removal of <br />uranium, tecnitium-99, iodine-129, carbon <br />tetrachloride, TCE, chloroform and other minor VOCs, <br />and nitrate. The treatment system also utilized a <br />combination of varied technologies including ion <br />exchange, biological treatment with fluidized bed and <br />membrane biological reactors, and air stripping with <br />off gas carbon adsorption. The design team and the <br />Department of Energy won distinguished awards for <br />the advanced features and multimedia approach to <br />treatment needs. <br />Brackish Water Recovery Cation and Anion Ion <br />Exchange I Green Meadows Water Treatment Plant <br />(WTP) I Brine Regeneration* I Technical Expert <br />To expand and improve the existing facilities at the <br />Green Meadows Water Treatment Plant (WTP), Lee <br />County Utilities' evaluation confirmed the need to <br />design the source water facilities using Upper <br />Floridan Aquifer (UFA) well water and selected a new <br />reverse osmosis (RO) process for the expanded <br />facility. Ion exchange (IX) was selected to treat the <br />surficial aquifer water in lieu of the existing lime <br />softening treatment because local high salinity <br />groundwater is used to IX regeneration. The <br />proposed facility has a firm finished water capacity of <br />14 MGD with maximum treatment capacity of 16 <br />MGD. Ken provided the ion exchange expertise for <br />the detailed design of both IX systems, guiding junior <br />and mid -level engineers through the drawings and <br />narrative specifications preparation. Brine <br />regenerated cation IX columns were provided for <br />hardness and iron removal and anion IX columns <br />were provided for sulfate and organics removal. <br />Confidential Mine* I California I Technical Expert <br />Ken provided water treatment and reuse expertise for <br />a study of remediation alternatives for 300 to 600 <br />GPM of high salinity groundwater with an average <br />TDS about 13,000mg/L. Ken developed a process <br />scheme to desalinate the pit lake water to below <br />1,500 thermal processes and without generating <br />liquid concentrate (reverse osmosis concentrate) <br />and resulting in a significant reduction of CAPEX <br />and OPEX cost relative to client's prior concept <br />design that included thermal crystallization. The <br />desalinated water met targets to allow reuse for local <br />agricultural needs. <br />Incirlik AB-2007 AFCEE 4P (Ion Exchange <br />Softening)* I Lead Process Engineer <br />Ken was involved in the design of a IX water <br />softening system to treat the entire base potable <br />water supply (2,000 GPM). The system used ion <br />exchange and provided for the regeneration of the ion <br />exchange resins onsite. The ion exchange vessels, <br />brine tank and waste brine tank were housed in a <br />single new building. The system was design to be <br />fully automated for backwashing, resin regeneration <br />using brine, and rinsing. <br />Confidential Refinery I Ion Exchange Optimization <br />and Flow Increase Study* I Senior Technical <br />Consultant I Minnesota I Lead Process Engineer <br />Multiple capital projects were implemented which will <br />consume additional well water for either steam <br />generation or cooling water utilities. The Refinery <br />wanted to augment or optimize the existing <br />demineralized water treatment system to treat the <br />additional well water to meet boiler feed water <br />specifications. The existing boiler feedwater system is <br />comprised of chlorination with multi -media filtration for <br />iron removal, RO for initial demineralization, and <br />cation ion exchange (IX), degasification, and anion IX <br />for final demineralization (IX System), The primary <br />finished water targets cannot exceed a specific <br />conductivity, specified by the Boiler House <br />Operations, and silica below 0.25 mg/L. <br />denotes projects completed with other firms <br />City of Santa Ana', On -Call Engineering Design Services for PFASTreatment Systems RFP 110. 22-133 A-16 <br />
